There's a roughly linear relationship between the length of someone's femur (the long leg-bone in your thigh) and their expected height. Within a certain population, this relationship can be expressed using the formula h=2.39f+62, where hh represents the expected height in centimeters and ff represents the length of the femur in centimeters. What is the meaning of the hh-value when f=46f=46? 1 .The expected height for someone with a femur length of 171.94 centimeters.

2. The femur length for someone with an expected height of 46 centimeters.

3. The change in expected height for every one additional centimeter of femur length.
